A "green" and durable precast cinder block

Our carbon negative cinder block has everything going for it: It's safe, sturdy, and green! Not only is our construction-grade cinder block produced using the CarbiCrete process not emitting CO2 into the air, but it traps it, too. This is why we call it carbon negative. Meeting all industry specifications and the ASTM C90 standard, our no-cement precast cinder block is as efficient, and has an equal, if not greater, load-bearing capacity than blocks made of cement. Choosing the cement-free CarbiCrete cinder block for your construction project can help you obtain LEED certification.


20 blocks produced = 1 tree planted, in terms of CO2 emissions reductions.

Safe and Sturdy
